Greatest Common Factor
We found the factors 621,681,264 . The biggest common factor number is the GCF number.
So the greatest common factor 621,681,264 is 3.
Lets's calculate LCM of 89,31,154
Given numbers has no common factors except 1. So, there LCM is their product i.e 424886
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/424886
Therefore, the GCF of Fractions 621/89,681/31,264/154 is 3/424886
The formula of LCM is LCM(a1,a2,a3....,an) = ( a1 × a2 × a3 × .... × an) / GCF(a1,a2,a3....,an) x common factors(if more than 2 numbers have common factors).
We need to calculate greatest common factor of 89,31,154 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(89,31,154) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(89,31,154) x common factors =1 x 1 = 1
LCM(89,31,154) = ( 89 × 31 × 154 ) / 1
LCM(89,31,154) = 424886 / 1
LCM(89,31,154) = 424886
Here are some samples of GCF of Fractions calculations.
